Personalized Moon Crash

Ich Bin Zu writes "Do you want to create your own crater on the moon? CNN has an article about a company putting a personalized moon crash for sale on ebay. The bid opens with $6 million which will enable the highest bidder to stuff up to 10kg worth of stuff on a space craft and lob it to the moon. The condition of the cargo is not guaranteed as it crashes on the moon at 4000 mph."

Info about company and founder

The company is Orbital Development.

Gregory Nemitz is an interesting character. I am a little skeptical about the deal since you are purchasing a "project" and not an actual mission. So there are very few guarantees attached, and you have limited authority of the project.

I think Nemitz's more interesting project is the most credible attempt to assert ownership over an extraterrestrial body. Specifically, he is asserting his claim over the near earth asteroid Eros.

On his website you can see legal correspondence between him and NASA as he gives them an invoice for a parking fee for their NEAR spacecraft that crash landed on the asteroid. Also available is his explanation of what he is doing and why he is doing. A very interesting read, and it gives some in-depth analysis of the nature of property ownership.

Well, the parking fee is just a premise to get a declaration of ownership from the federal government. The invoice is like $10 per century, so its not really anything to get up in arms for.

So NASA said there claims are without basis. Then state department says it violates the Outer Space Treaty, however that only applies to governments annexing extra terrestrial bodies and doesn't apply to private citizens.

So now he's involved in litigation and his argument is based on some complex legal theory that I don't pretend understand called work-equity. You can think of like it homesteading, where you squat a piece of land, and put development in it. After a while, the government recognizes your claim because of all the work you put in it. However, Nemitz isn't physically at the asteroid. Possession is 9/10th of the law, but he doesn't have possession, so his legal arguments are based on other 1/10th.

Anyway, though his claims may be dubious, his goal is to set a legal precedent for this kind of thing where one does not currently exist. This will give investors a clearer understanding and more certain environment of the legal framework for space property where one does not currently exist.

Good question. 4000 mph ~= 1800mps, KE = .5(10)(1,800)^2 = 16 megajoules. Perfectly elastic collision gets you a PE = 16 MJ = 10 kilograms * 9.8/6 * height, so the height would be...damn, a million meters? That's pretty friggin' high.

Why ship it to the moon to incinerate it... you could just nudge it out of earth's orbit and let the sun pull it the rest of the way in and it'll be vaporized.

From what I understand it actually takes more energy to send something from Earth orbit into the Sun than it would take to send the object on a path to escape the solar system. This is because in order to crash into the Sun you first have to cancel out the velocity imparted by being in Earth's orbit around the Sun in the first place. However if you wanted to leave the solar system you would simply add some velocity to your orbit around the Sun and this would kick you to an orbit further from the Sun.

In other words the quantity of energy needed to lower your orbital velocity to zero relative to the Sun would be less than the amount you need to add to escape from orbiting the Sun. This means that it probably takes less energy to send something to the Moon than it would take to send it to the Sun.

According to my quick calculations it would take a velocity of approximately 42 km/s to escape the solar system from Earth's orbit. Earth imparts a velocity of approximately 30 km/s to any object which is in a similar orbit around the sun. This means that you would need to either slow down by 30 km/s to hit the sun (30 km/s - 0 km/s) or you would need to speed up by 12 km/s to leave the solar system (42 km/s - 30 km/s).

Strange, but true - it actually takes less energy to leave the solar system than it is to crash into the sun from Earth orbit. This, of course, is not counting stuff like orbital slingshots around other planets and such which could decrease the energy needed for both crashing the Sun and leaving it.

Here's the site where I got some of the data I used for my calculations, as well as the formulas for escape velocity and such.
